Hmm...I wonder why mine has crashed...It's just doing simple things like opening an app, pushing the power button to turn it off, using the Google search widget and so forth. I'll try Tiamat out. Would having a new kernal solve some of these issues?
As a side note though, I have seen a performance increase since rooting. The menus still seem to have a slight lag, but a lot less noticable than Sense. Not having all of the bloatware suck up 80% of my RAM, having the extra 100mhz from overclocking and probably the Android 2.3 update really makes a difference with games though, I love it!
